yes! But the pkg was not the easiest to compile without the trick below

Okay, nice! Actually, I had similar problems with a few other packages 
which have complicated depedencies too (rgl, Rgtk2, rpvm) and could not 
compile them, but using the  build-dep trick I could finally update them 
from within R!

But I feel that using this method I install many more packages than 
required actually... no? Do you think it would be possible to update 
them once? I know it is unfortunately much more cumbersome to do this on 
Ubuntu than on Debian :-(

Thanks a lot!!
